yeah but you could have just said
low pass = lets low frequencies through and blocks frequencies above it.
High pass = lets high frequencies through and blocks frequencies below it
band pass (not auxy) = can amplify and de-amplify frequencies depending on how you use them

I understood it all too, but that’s just because i’ve used them before and know what they mean, but if you’re not sure about how to use those tools then i think you’d get lost on that paragraph pretty quick
